Effect Of Different Extrusion Processing Parameters On Physical Properties Of Soy White Flakes And High Protein Distillers Dried Grains-Based Extruded Aquafeeds, Sushil Kumar Singh, Kasiviswanathan Muthukumarappan Apr 2018

Effect Of Different Extrusion Processing Parameters On Physical Properties Of Soy White Flakes And High Protein Distillers Dried Grains-Based Extruded Aquafeeds, Sushil Kumar Singh, Kasiviswanathan Muthukumarappan

Sushil Singh

Nutritionally balanced ingredient blends for catla (Catla catla), belonging to the family Cyprinidae, were extruded using single screw extruder. The extrusion was carried out at five levels of soy white flakes content (21%, 29%, 40%, 52%, and 59% db), five levels of moisture content (15, 19, 25, 31, and 35% db) and five levels of barrel temperature (100, 110, 125, 140, and 150 ºC) using three different die nozzles (having L/D ratios 3.33, 5.83, and 7.25). Blends with net protein content of 32.5% contains soy white flakes, along with high protein distillers dried grains (HP-DDG), corn flour, corn gluten meal, …

Influence Of Processing Conditions On Apparent Viscosity And System Parameters During Extrusion Of Distiller’S Dried Grains-Based Snacks, Poonam Singha, Kasiviswanathan Muthukumarappan, Padmanaban Krishnan Dec 2017

Influence Of Processing Conditions On Apparent Viscosity And System Parameters During Extrusion Of Distiller’S Dried Grains-Based Snacks, Poonam Singha, Kasiviswanathan Muthukumarappan, Padmanaban Krishnan

POONAM SINGHA

A combination of different levels of distillers dried grains processed for food application (FDDG), garbanzo flour and corn grits were chosen as a source of high-protein and high-fiber extruded snacks. A four-factor central composite rotatable design was adopted to study the effect of FDDG level, moisture content of blends, extrusion temperature, and screw speed on the apparent viscosity, mass flow rate or MFR, torque, and specific mechanical energy or SME during the extrusion process. With increase in the extrusion temperature from 100 to 140°C, apparent viscosity, specific mechanical energy, and torque value decreased. Increase in FDDG level resulted in increase …

Physicochemical And Nutritional Properties Of Extrudates From Food Grade Distiller’S Dried Grains, Garbanzo Flour, And Corn Grits, Poonam Singha, Sushil Kumar Singh, Kasiviswanathan Muthukumarappan, Padmanaban G. Krishnan Dec 2017

Physicochemical And Nutritional Properties Of Extrudates From Food Grade Distiller’S Dried Grains, Garbanzo Flour, And Corn Grits, Poonam Singha, Sushil Kumar Singh, Kasiviswanathan Muthukumarappan, Padmanaban G. Krishnan

Sushil Singh

Distiller’s dried grains and garbanzo flour were blended with corn grits for the development of extruded snacks using a single screw extruder. Distiller’s dried grains were processed for food application and termed as food grade distiller’s dried grains or FDDG. Effects of different level of FDDG addition (0%–20%) and extrusion process parameters such as barrel and die temperature (100–140°C), screw speed (100–200 rpm), and feed moisture content (14%–20% wet basis) on the physical properties (expansion ratio, bulk density, color parameters), functional properties (water absorption and solubility indices), and nutritional properties (total dietary fiber, soluble and insoluble dietary fiber and protein …
